Description

Technical Field

[0001] This utility model relates to the field of T-con board technology, and in particular to a T-con board structure for liquid crystal displays. Background Technology

[0002] With the rapid development of intelligent connected vehicle technology, in-vehicle displays have become a core component of modern vehicle human-machine interaction systems, and T-con boards have become a key component for displaying video image signals on in-vehicle displays. The main function of the T-con board is to receive video signals and clock signals from the digital board, convert the received video signals into data signal form used by the data drive circuit, and transmit them to the data drive circuit. At the same time, it controls the data drive circuit to turn on at the appropriate time so that the screen can recognize and display them correctly.

[0003] The method of using ribbon cable lamination to connect the ribbon cable and the T-con board is complex in terms of process and not conducive to installation and disassembly. The lamination process can also affect the T-con board itself, thus affecting the reception of video and clock signals, and in severe cases, directly affecting the screen display. Moreover, it can only be fixed in one form, which greatly increases the difficulty of later maintenance. Due to the limitations of the T-con board and the use of dual ICs and dual ribbon cables in ribbon cable lamination, not only is the cost greatly increased, but the yield rate cannot be guaranteed, and it also seriously affects the production efficiency and product reliability of automotive modules. Utility Model Content

[0004] The main purpose of this invention is to provide a T-con board structure for liquid crystal displays, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a T-con board structure for a liquid crystal display includes a display screen and a T-con board. The display screen is connected to a first FPC cable for connecting the T-con board. The T-con board is also provided with a fixing component. The T-con board is provided with a first connector located outside the fixing component. The first connector is detachably connected to the first FPC cable. The T-con board is also provided with a second connector, which is detachably connected to a second FPC cable.

[0006] Further configuration: The first FPC cable and the second FPC cable are respectively plugged into the first connector and the second connector.

[0007] Further configuration: A metal plate is provided between the T-con board and the display, and a planar recess is provided in the middle of the metal plate for placing the T-con board.

[0008] Further configuration: The metal plate is provided with tape one and tape two. Tape one covers the T-con board and the first FPC cable, and tape two covers the second FPC cable.

[0009] Compared with the prior art, this utility model has the following beneficial effects: This utility model achieves quick and convenient installation by connecting the first connector and the second connector on the surface of the T-con board to the first FPC cable and the second FPC cable respectively. Utilizing the installable and detachable characteristics of the first connector and the second connector, it can be used entirely according to customer needs. The installation using the first connector and the second connector effectively solves the complex process of the T-con board and effectively solves the problem of high risk and impact on the T-con board caused by normal cable crimping. At the same time, by connecting the first connector and the second connector to the first FPC cable and the second FPC cable respectively, the original dual IC is changed to a single IC by utilizing the characteristics of the FPC cable, which reduces the labor and material costs of the module. The connection of the first connector and the second connector to the first FPC cable and the second FPC cable respectively effectively improves the production efficiency and product reliability of the vehicle module.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] like Figure 1-2As shown, to achieve the above objectives, the technical solution adopted by this utility model includes: The entire structure is provided with a metal plate 8, which serves as a barrier and also protects the back of the display screen 1. A flat recess 81 is provided in the middle of the metal plate 8 for placing the T-con plate 2. This flat recess 81 forms a position for placing the T-con plate 2, preventing it from protruding and effectively reducing the overall thickness. A first connector 4 and a second connector 6 are provided on the T-con plate 2, enabling insertion and connection with the first FPC cable 3 and the second FPC cable 7. This changes the previous press-fit connection method, allowing the first connector 4 and the second connector 6 to independently connect to the first FPC cable 3 and the second FPC cable 7 outside of the fixed component 5. This also changes the previous dual-IC style to a single-IC style, avoiding the need for press-fit fixing and thus improving the product's yield rate. Furthermore, by covering the T-con board 2 and the first FPC cable 3 on the metal plate 8 with tape 91 and the second FPC cable 7 with tape 92, the entire T-con board 2, the first FPC cable 3, and the second FPC cable 7 can be fixed on the metal plate 8. In addition, wrinkles on the first FPC cable 3 and the second FPC cable 7 are avoided so as not to affect communication.

[0014] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
